          It's not necessary to reset OST object's version. Next time when the OST objects are enabled to write, the MDS should send RPCs to the OST and at that time, the LU_LAYOUT_RESYNC flag will be cleared. The hidden reason behind this is that we don't want to send unnecessary RPCs from the MDS to OSS because it's expensive by doing so.
